MarketCore Community

✦ MarketCore Community

Most Minecraft auction plugins struggle with race conditions, disconnect dupes, and ghost items when servers lag or restart. MarketCore was engineered from the ground up to solve this.
Built with an atomic transaction journal and safe escrow persistence, MarketCore guarantees that no money or item is ever lost or duplicated, even during sudden crashes.


Key Features

• Transaction-Safe & Zero-Dupe Architecture: All actions are backed by atomic state machines (PENDING ➔ IN_PROGRESS ➔ RESOLVED).
• Claims Mailbox (/market claim): Purchases and payouts are securely held in durable offline storage until claimed by the player.
• Clean, Modern 54-Slot GUI: Optimized 36-item dense grid, explicit sorting, search filters, and intentional confirmation dialogues.
  
  
  
  
  ​
• High Performance & Low Overhead: Lightweight vanilla sounds, zero repeating cosmetic tasks, and asynchronous database queries.
• Dual Storage Engine: Built-in zero-config SQLite (WAL mode) or high-throughput MariaDB/MySQL with HikariCP.
• 6 Built-in human-made translations: English, Spanish, Brazilian Portuguese, French, German, and Simplified Chinese with automatic player locale detection.
• Admin Audit & Reconciliation: Complete transaction traceability (/market admin tx <id>) and manual resolution tools for ambiguous economy events.

Native Human-Crafted Localization
